#
# Xiph.org maintains the Ogg streaming standard and Vorbis audio compression
# format, amongst others. The ICEcast server is an alternative to SHOUTcast.
# But it turns out, that Xiph lists only MP3 streams, no OGG. And the directory
# is less encompassing than Shoutcast.

# format, amongst others. The ICEcast server is an alternative to SHOUTcast.


#
# It meanwhile provides a JSOL dump, which is faster to download and process.
# So we'll use that over the older yp.xml. (Sadly it also doesn't output
# homepage URLs, listeners, etc.)
